The aim of this study was to investigate the echographic, therapeutic and evolutionary aspects of ventricular septal defects (VSD) in the general cardiology department of the Hôpital National Ignace Deen. Methods: A retrospective data collection was carried out from January 2018 to December 2023 including 85 cases of isolated IVC was performed. The variables studied were epidemiological, clinical, paraclinical, therapeutic and evolutionary. Results: Of the 320 patients seen during the study period for congenital heart disease, 85 (26.556%) were isolated IVCs. Age at diagnosis ranged from 3 months to 16 years, with an average age of 3.59 years. The most represented ethnic group was the Fulani (50.58%). The 8.24% came from consanguineous marriage versus 22.35%. 91.76% of children had a history of bronchitis. The most common clinical signs found were systolic murmur (90.58%), growth retardation (51.76%). Only 4 cases (4.70%) had a malformation associated with IVC represented by DiGeorges disease (2.35%) and trisomy 21 (2.35%). Nearly half the patients had type IIb VIC (44.71%). The other half were represented by type 1 (18.82%), type IIa (20%), type III (10.59%) and type IV (5.88%). According to site more than two-thirds of VICs (71.64%) were perimembranous in location, followed by infundibular (16.47%) and muscular (11.76%) VICs. In our study 55.29% presented an indication for both surgical intervention and medical treatment, while 16.47% required only medical treatment. In contrast, 28.23% were placed under exclusive surveillance. Of the 47 patients for whom surgery was indicated, 29 (61.17%) underwent surgical repair, while 18 (38.83%) were awaiting confirmation for surgery. Conclusion: VIC is the most common congenital heart disease. An early detection strategy and the establishment of specialized centers could improve the outcome of these children.展开更多

Methods:Sixty- two patients (10 to 55 years of age) were selected for percutaneous closure of ASD bytrans-esophageal echocardiography, which was also used to monitor the procedure, to select theappropriate size of the Amplatzer device, to verify its position, and to access the immediateresults of the procedure. During the follow-up, transthoracic echocardiography (TTE) or TEE was usedto evaluate the presence and magnitude of residual shunt (RS), device position, and right cardiacchamber diameters. Results: The mean ASD diameter by TTE ([19. 1 +- 5. 8] mm) was significantlysmaller (P< 0. 001) than the stretched diameter of the ASD (25. 1 +- 6. 4) mm. There are nosignificant differences between the TEE -measured value (23. 5+_6. 2) mm and the stretched diameterof the ASD (P > 0. 05). Due to proper patient selection all procedures were successful. There wasimmediate and complete closure in 61/62 patients, only one patients had trivial residual shunt.Follow- up was performed using TTE or TEE right after operation, 1 d, 1 month, 3 months, 6 monthsand yearly thereafter. Ail, patients remain asymptomatic without any clinical or technical problems.Conclusion: With the aid of TEE, percutaneous closure of ASD can be performed successfully, safely,and effectively.展开更多

Methods: Patients with PDA (n = 25) and ASD ( n = 16), confirmed byechocardiography, were treated by transcatheterization. Amplatzer occluder device was placed by thetranscatheterization with the image support of X-ray and transthoracic echocardiography ( TTE) . TheTTE, ECG and X-ray examination were engaged to evaluate the therapeutic results on the time pointsof 24 h , 1, 3 , 6, 12 months after the operation, and all these cases were engaged to the follow-upexamination. Results: The cardioangiographic diameter was 13.0-28.0 mm ([19.3+-4.9] mm) in ASD and2.0-7.7 mm ([3.9+-1.5] mm) in PDA . The diameter of the Amplatzer occluder selected were 13.0-30.0mm ( [20.6+-5.1] mm) in ASD and 4.0-12.0 mm ([6.6+-1.9] mm) in PDA , respectively. All the Amplatzeroccluders were placed successfully. There were no complications during and after the operation.Very small residual shunt was still found soon after the operation in 10 cases , and there were noresidual or recanalization after three months of the operation. The pulmonary artery pressure andheart size were significantly decreased in follow-up examination . Conclusion: Transcatheteringclosure with Amplatzer device is an effective, simple and safe technique in the treatment of ASD andPDA in children.展开更多

Atrial septal defect （ASD） is one of the most common defects of CHD. Previous studies have demonstrated that mutations in the transcription factor T-box 20 （TBX20） contribute to congenital ASD. Whole-exome sequencing in combination with a CHD-related gene filter was used to detect a family of three generations with ASD. A novel TBX20 mutation, c.526G〉A （p.D176N）, was identified and co-segregated in all affected members in this family. This mutation was predicted to be deleterious by bioinformatics programs （SIFT, Polyphen2, and MutationTaster）. This mutation was also not presented in the current Single Nucleotide Polymorphism Database （dbSNP） or National Heart, Lung, and Blood Institute （NHLBI） Exome Sequencing Project （ESP）. In conclusion, our finding expands the spectrum of TBX20 mutations and provides additional support that TBX20 plays important roles in cardiac development. Our study also provided a new and cost-effective analysis strategy for the genetic study in small CHD pedigree.展开更多

Methods Between September 2011 and February 2013, we collected 40 patients who underwent perventricular closure via a small lower sternal incision(minimally invasive group), aged 15.5±3.5 years(12 months to 32 years) with a body weight of 24.2±7.5 kg(10.8-58.0 kg). The mean size of VSD was 5.6±0.5 mm(2-14 mm). Another 40 patients were included as the surgical group, receiving the conventional surgical repair of VSD. The device of the minimally invasive group was released under the guidance of transesophageal echocardiography. Success rate, cardiac indicators, and clinical outcomes of the 2 groups were compared. Results The patients in the surgical group and those in the minimally invasive group showed similar results in success rate(both 97.5%). The procedure time, intensive care unit stay, hospital stay, and postoperative recovery time in the minimally invasive group were significantly shorter than those in the surgical group(58±21 minutes versus 145±26 minutes, 2±1 days versus 8±3 days, 5±1 days versus 16±6 days, 3±1 days versus 90±20 days, all P<0.05). The minimally invasive group had a higher incidence of conduction anomalies(17.5% versus 2.5%, P<0.05). In the follow-up period of 3-12 months, there was no new residual shunt, noticeable aortic regurgitation, significant arrhythmias, or device failure except for new complications in the surgical group. Conclusions The success rate of minimally invasive perventricular device closure of VSD under transesophageal echocardiography guidance is similar to that of conventional surgical repair, but the short-term outcomes of the minimally invasive approach is much better. Long-term follow-up is necessary to confirm the effectiveness of this technique.展开更多

Nine months later, the patient suffered from chest distress, palpitation, and sweating at daily activities, and her 6-min walk distance decreased significantly （155 m）. Her echocardiography showed increased left ventricular end-diastolic diameter with left ventricular ejection fraction of 37%. Her symptoms reduced significantly one week after received cardiac resynchronization therapy. She had no symptoms at daily activities, and her echo showed left ventricular ejection fraction of 46%and 53%. Moreover, left ventricular end-diastolic diameter decreased 6 and 10 months after cardiac resynchronization therapy, and 6-min walk dis-tance remarkably increased. This case demonstrated that persistent complete left bundle branch block for nine months after transcatheter closure with ventricular septal defect Amplatzer occluder could lead to left ventricular enlargement and a significant decrease in left ventricular systolic function. Cardiac resynchronization therapy decreased left ventricular end-diastolic diameter and increased left ventricular ejection fraction, thereby improving the patient’s heart functions.展开更多

文摘Congenital atrial septal defect(ASD)with severe scoliosis is a rare compound malformation inchildren.Severe sco liosis should be corrected as soon as possible.The growth rod is suitable for patients withearly scoliosis and obvious scoliosis under 10 years old.However,the fluoroscopic radiopaque of titaniumalloy plate will inevitably partly make the operative field of interventional occlusion blind.We presenta7-year-old Chinese girl with ASD and scoliosis who underwent spinal correction with a dual-growthrod.In this case,we performed transcatheter closure of ASD solely under the guidance of transthoracicechocardiography.Transthoracic echocardiography(TTE)has been reported as efficacious and safe forassessment and guidance of ASD occlusion.For patients with visual field occlusion under fluoroscopy,theapplication of TTE is efficacious and safe for assessmnent and guidance of ASD occlusion.
文摘BACKGROUND The Food and Drug Administration has approved percutaneous atrial septal defect(ASD)and patent foramen ovale(PFO)closure devices for hemodynamically significant interatrial shunts,paradoxical emboli including stroke,and decompression sickness.We aimed to study the trends in utilization and reimbursements of transcatheter ASD/PFO closure devices.AIM To analyze trends in utilization and Medicare reimbursements for transcatheter ASD/PFO closure procedures from 2013 to 2022.METHODS A query of administrative data on United States Medicare beneficiaries undergoing transcatheter ASD/PFO was conducted from 2013 to 2022 using the Centers for Medicare and Medicaid Services Part B National Summary Data File.Inflation adjustments were made using the 2023 Consumer Price Index.Trend analysis was quantified using growth rate and simple linear regression calculations.All analyses were performed using Microsoft Excel 16.77.1(2023).RESULTS The annual number of transcatheter ASD/PFO closure procedures increased by 81%since 2013,with an average yearly growth rate of 44%cases per year(P<0.001).Annual Medicare reimbursements for transcatheter ASD/PFO therapies mirrored the annual procedure trends.The per-case reimbursements decreased by 18%,i.e.,$1128.80 in 2013 and$770.21 in 2022(P<0.001).There was a significant drop in the number of procedures in the year 2020,which correlates to the onset of the coronavirus disease 2019 pandemic,followed by a sharp uptick in the number of cases in 2021 and 2022.CONCLUSION Medicare utilization of transcatheter ASD/PFO closure therapies has grown significantly in procedural volume from 2013 to 2022.However,this has been accompanied by a decrease in per-case reimbursements.

文摘Background:Totally thoracoscopic surgery(TTS)and right lateral thoracotomy(RLT)are both extensively utilized in the surgical repair for atrial septal defect(ASD).However,RLT is generally considered in low-weight pediatric patients as a result of restricted surgical exposure.This study aims to introduce an RLT approach for ASD repair in adults and compare its clinical outcomes with TTS.Methods:We conducted a retrospective analysis of the clinical data of 23 adult patients who underwent ASD repair at Guangdong Provincial People’s Hospital between June and October 2024.Patients were divided into two groups based on the surgical approach they adopted:group totally thoracoscopic surgery(TTS,n=12)and group right lateral thoracotomy(RLT,n=11).All individuals finished a follow-up three months after surgery.Operative parameters,postoperative courses,echocardiographic measurements and laboratory investigations were compared between the two groups.Results:The total surgical duration was significantly longer in group RLT compared with group TTS[(234.00±47.93)min vs.(175.17±52.36)min,p=0.011].Group RLT exhibited a significantly higher respiratory index(RI)at<6 h postoperatively(1.00±0.58 vs.0.30±0.37,p=0.01)and significantly lower levels of soluble suppression of tumorigenicity 2(sST2)[(136.61±43.12)ng/mL vs.(199.08±33.56)ng/mL,p=0.037]and cardiac troponin(cTnT)[(277.04±89.85)pg/mL vs.(343.30±482.40)pg/mL,p=0.047]at 12-24 h postoperatively.Echocardiographic measurements showed no significant differences between two groups,except for a more pronounced reduction in left atrial(LA)size at discharge in group TTS[(5.00±3.64)mm vs.(0.09±4.44)mm,p=0.008].Conversely,group RLT demonstrated a less significant decrease in glutamyl transpeptidase(GGT)[(1.00±6.00)U/L vs.(5.25±3.86)U/L,p=0.026]but a more significant decrease in blood urea nitrogen(BUN)[(1.81±1.10)mg/dL vs.(0.81±1.07)mg/dL,p=0.038].Conclusions:RLT for ASD repair in adults demonstrated comparable clinical outcomes to TTS in terms of postoperative recovery and cardiac function and also produced fewer scars than TTS.Our study proved the feasibility,safety and cosmetic effects of uniport RLT for ASD repair in adults when compared with TTS.
文摘Residual atrioventricular valve regurgitation after correction of complete atrioventricular septal defect(cAVSD)is still not ideal.As a modification of the double-patch method,our technique comprises a suture-bite-wide strip of a third patch that is incorporated to the upper margin of the left side of the ventricular septal defect(VSD)patch.This third patch counteracts not only the valvular tissue loss caused by the suture bites but also the rightward displacement of the VSD patch in a bulged fashion that occurs with increased left ventricular pressure after weaning from cardiopulmonary bypass.This unfavorable outcome was addressed with the current technique through augmentation of the left-sided bridging leaflets serving to prevent the separation of them from their corresponding mural leaflets.The concept was applied in two cases with Down syndrome aged 5 months and 6 months,respectively,as a rescue procedure in the same session just after a failed cAVSD repair.Since the immediate-and short-term outcomes of the atrioventricular valves in regard to regurgitation are satisfying,we believe that the technique proposed herein holds promise for the future in terms of tackling residual atrioventricular valve regurgitation.

文摘Background:Atrial septal defect(ASD)is a common form of adult congenital heart disease that can lead to long-term adverse outcomes if left untreated.Early closure of ASD has been associated with excellent outcomes and lower complication rates.However,there is limited evidence regarding the prognosis of ASD closure in older adults.This study aims to evaluate the mortality rates in older ASD patients with and without closure.Methods:A retrospective cohort study was conducted on patients aged 40 years or older with ASD between 2001 and 2017.Patients were followed up to assess all-cause mortality.Univariable and multivariable analyses were performed to identify the predictors of mortality.A p-value of<0.05 was considered statistically significant.Results:The cohort consisted of 450 patients(mean age 56.6±10.4 years,77.3%female),with 66%aged between 40 and 60 years,and 34%over 60 years.Within the cohort,299 underwent ASD closure(201 with transcatheter and 98 with surgical closure).During the median follow-up duration of 7.9 years,51 patients died.The unadjusted cumulative 10-year rate of mortality was 3%in patients with ASD closure,and 28%in patients without ASD closure(log-rank p<0.001).Multivariable analysis revealed that age(hazard ratio[HR]1.04,95%confidence interval[CI]1.006–1.06,p=0.01),NYHA class(HR 2.75,95%CI 1.63–4.62,p<0.001),blood urea nitrogen(BUN)(HR 1.07,95%CI 1.03–1.12,p<0.001),right ventricular systolic pressure(RVSP)(HR 1.07,95%CI 1.003–1.04,p=0.01),and lack of ASD closure(HR 15.12,95%CI 5.63–40.59,p<0.001)were independently associated with mortality.Conclusion:ASD closure demonstrated favorable outcomes in older patients.Age,NYHA class,BUN,RVSP,and lack of ASD closure were identified as independent factors linked to mortality in this population.

文摘Background:The optimal surgical timing and clinical outcomes of ventricular septal defect(VSD)closure in neo-nates remain unclear.We aimed to evaluate the clinical outcomes of VSD closure in neonates(age≤30 days).Methods:We retrospectively reviewed 50 consecutive neonates who underwent VSD closure for isolated VSDs between August 2003 and June 2021.Indications for the procedure included congestive heart failure/failure to thrive and pulmonary hypertension.Major adverse events(MAEs)were defined as the composite of all-cause mortality,reoperation,persistent atrioventricular block,and significant(≥grade 2)valvular dysfunction.Results:The median age and body weight at operation were 26.0 days(interquartile range[IQR],18.8–28.3)and 3.7 kg(IQR,3.3–4.2),respectively.The median follow-up duration was 110.4 months(IQR,56.8–165.0).Seven patients required preoperative respiratory support,andfive had significant(≥grade 2)preoperative valvular dysfunction.One early mortality occurred due to irreversible cardiogenic shock;no late mortality was observed.One reopera-tion was due to hemodynamically significant residual VSD at 103.8 months postoperatively.The overall survival,freedom from reoperation,and freedom from MAE at 15-years were 98.0%,96.3%,and 94.4%,respectively.Pre-operative mechanical ventilation was associated with a longer duration of postoperative mechanical ventilation(p<0.001)and a longer length of intensive care unit stay(p<0.001).Conclusions:VSD closure with favorable outcomes without morbidities is feasible even in neonates.However,neonates requiring preoperative respiratory support may require careful postoperative management considering the long-term postoperative risks.Overall,surgical VSD closure might be indicated earlier in neonates with respiratory compromise.
文摘Objectives:To explore the feasibility and efficacy of electrophysiology guidance for transcatheter closure of perimembranous ventricular septal defect(PmVSD)in adults.Methods:Adult patients with PmVSD who underwent transcatheter in Guangdong Provincial People’s Hospital,Guangdong Cardiovascular Institute from February 2016 to January 2018 were selected.The distribution of the His-Purkinje system(HPS)close to the margins of PmVSD in the left ventricle was identified using three-dimensional(3D)electro-anatomic mapping and near-field HPS was further confirmed by different pacing protocols.The follow-up protocol included electrocardiogram(ECG)and transthoracic echocardiography at 6,24,72 h,1,3,6 months and 1,2,3,5 years after the procedure.Results:Of the 21 patients in the study,with an average age of 28.1 years,61.9%were female and 38.1%were male.Eighteen patients(85.7%)successfully underwent transcatheter intervention.The minimum distance between the margins of the PmVSD and near-field HPS ranged from 2.5±0.7(1.3~3.9)mm.An average follow-up period was 4.1±1.3(0.25~5)years,median of which was 5 years.1,3,5-year follow-up rate was 95.2%,90.4%and 52.4%,respectively.At the end of the follow-up,ECG abnormalities were observed in 5 cases(23.8%),including left anterior hemiblock(LAH)in 3 cases(14.3%),incomplete right bundle branch block and LAH in 1 case(4.8%),premature atrial contraction in 1 case(4.8%).Mild tricuspid regurgitation(TR)and mild TR with mild mitral regurgitation with mild aortic regurgitation was observed in 1 case(4.8%),as well as left ventricular diastolic dysfunction.Conclusions:The study indicates that the results have guiding significance for transcatheter closure of PmVSD guided by 3D electro-anatomic mapping technique.However,this method requires a larger amount of clinical research data to support.
文摘Background and Objective:The most feared complication of uncorrected secundum Atrial Septal Defect(ASD)is pulmonary arterial hypertension(PAH).Pulmonary vascular resistance(PVR)is crucial in detecting precapil-lary pulmonary hypertension(PH)to guide the need for PAH-specific therapy.There is a change in the cut-off value of PVR according to the recently updated PH guideline.How echocardiographic PVR(PVRecho)correlates to PVR by right heart catheterization(RHC)(PVRcath)according to the new guidelines has not been known.The aim of this study is to determine the reliability of PVRecho in detecting PAH in Uncorrected Ostium Secundum ASD based on the current updated guideline and to help screen the high PVR group.Methods:429 ostium secun-dum ASD in the COngenital HeARt Disease in Adult and Pulmonary Hypertension(COHARD-PH)registry was divided into three groups according to the PVR.PVRecho was calculated using Abbas’Formula and compared the its gold standard,the PVRcath.The correlation between the two methods was analyzed.The Bland-Altman plot was used to analyze the agreement between the two methods.Receiver operating characteristics(ROC)analysis was used to determine the PVRecho cut-off value for high PVR.Results:The majority of the population(63.5%)had high PVR.Female gender dominated the study population(84%).PVR_(echo) was significantly correlated with PVRcath(r=0.6225,p<0.0001).Bland-Altman plot among all groups and in subgroups analysis showed a wide range of agreement.PVRecho underestimated PVRcath 5.124 WU.In subgroup analysis,PVRecho overestimated PVRcath 0.35 WU in those with PVR<2 WU.In the second and third groups,PVR_(echo) underestimated PVRcath 0.52 and 10.77 WU,respectively.Conclusion:PVRecho is reliable in predicting high PVR in uncorrected secun-dum ASD.However,there is a wide range of agreement.PVR_(echo) cut-off value of>1.62 WU showed good dis-criminatory power in determining high PVR.

文摘Background Atrial septal defect(ASD)is one of the most common congenital heart diseases.The diagnosis of ASD via transthoracic echocardiography is subjective and time-consuming.Methods The objective of this study was to evaluate the feasibility and accuracy of automatic detection of ASD in children based on color Doppler echocardiographic static images using end-to-end convolutional neural networks.The proposed depthwise separable convolution model identifies ASDs with static color Doppler images in a standard view.Among the standard views,we selected two echocardiographic views,i.e.,the subcostal sagittal view of the atrium septum and the low parasternal four-chamber view.The developed ASD detection system was validated using a training set consisting of 396 echocardiographic images corresponding to 198 cases.Additionally,an independent test dataset of 112 images corresponding to 56 cases was used,including 101 cases with ASDs and 153 cases with normal hearts.Results The average area under the receiver operating characteristic curve,recall,precision,specificity,F1-score,and accuracy of the proposed ASD detection model were 91.99,80.00,82.22,87.50,79.57,and 83.04,respectively.Conclusions The proposed model can accurately and automatically identify ASD,providing a strong foundation for the intelligent diagnosis of congenital heart diseases.
文摘Introduction: Ventricular septal defect (VSD) is the most common congenital heart disease of all congenital heart defects. The aim of this study was to investigate the echographic, therapeutic and evolutionary aspects of ventricular septal defects (VSD) in the general cardiology department of the Hôpital National Ignace Deen. Methods: A retrospective data collection was carried out from January 2018 to December 2023 including 85 cases of isolated IVC was performed. The variables studied were epidemiological, clinical, paraclinical, therapeutic and evolutionary. Results: Of the 320 patients seen during the study period for congenital heart disease, 85 (26.556%) were isolated IVCs. Age at diagnosis ranged from 3 months to 16 years, with an average age of 3.59 years. The most represented ethnic group was the Fulani (50.58%). The 8.24% came from consanguineous marriage versus 22.35%. 91.76% of children had a history of bronchitis. The most common clinical signs found were systolic murmur (90.58%), growth retardation (51.76%). Only 4 cases (4.70%) had a malformation associated with IVC represented by DiGeorges disease (2.35%) and trisomy 21 (2.35%). Nearly half the patients had type IIb VIC (44.71%). The other half were represented by type 1 (18.82%), type IIa (20%), type III (10.59%) and type IV (5.88%). According to site more than two-thirds of VICs (71.64%) were perimembranous in location, followed by infundibular (16.47%) and muscular (11.76%) VICs. In our study 55.29% presented an indication for both surgical intervention and medical treatment, while 16.47% required only medical treatment. In contrast, 28.23% were placed under exclusive surveillance. Of the 47 patients for whom surgery was indicated, 29 (61.17%) underwent surgical repair, while 18 (38.83%) were awaiting confirmation for surgery. Conclusion: VIC is the most common congenital heart disease. An early detection strategy and the establishment of specialized centers could improve the outcome of these children.
文摘Objective: To evaluate of the role of transesophageal echocardiography (TEE)in percutaneous closure of atrial septal defects (ASD) with the Amplatzer septal occluder. Methods:Sixty- two patients (10 to 55 years of age) were selected for percutaneous closure of ASD bytrans-esophageal echocardiography, which was also used to monitor the procedure, to select theappropriate size of the Amplatzer device, to verify its position, and to access the immediateresults of the procedure. During the follow-up, transthoracic echocardiography (TTE) or TEE was usedto evaluate the presence and magnitude of residual shunt (RS), device position, and right cardiacchamber diameters. Results: The mean ASD diameter by TTE ([19. 1 +- 5. 8] mm) was significantlysmaller (P< 0. 001) than the stretched diameter of the ASD (25. 1 +- 6. 4) mm. There are nosignificant differences between the TEE -measured value (23. 5+_6. 2) mm and the stretched diameterof the ASD (P > 0. 05). Due to proper patient selection all procedures were successful. There wasimmediate and complete closure in 61/62 patients, only one patients had trivial residual shunt.Follow- up was performed using TTE or TEE right after operation, 1 d, 1 month, 3 months, 6 monthsand yearly thereafter. Ail, patients remain asymptomatic without any clinical or technical problems.Conclusion: With the aid of TEE, percutaneous closure of ASD can be performed successfully, safely,and effectively.
文摘BACKGROUND An atrial septal defect is a common condition and accounts for 25%of adult congenital heart diseases.Transcatheter occlusion is a widely used technique for the treatment of secondary aperture-type atrial septal defects(ASDs).CASE SUMMARY A 30-year-old female patient was diagnosed with ASD by transthoracic echocardiography(TTE)1 year ago.The electrocardiogram showed a heart rate of 88 beats per minute,normal sinus rhythm,and no change in the ST-T wave.After admission,TTE showed an atrial septal defect with a left-to-right shunt,aortic root short-axis section with an ASD diameter of 8 mm,a parasternal four-chamber section with an ASD diameter of 9 mm,and subxiphoid biatrial section with a diameter of 13 mm.Percutaneous occlusion was proposed.The intraoperative TTE scan showed that the atrial septal defect was oval in shape,was located near the root of the aorta,and had a maximum diameter of 13 mm.A 10-F sheath was placed in the right femoral vein,and a 0.035°hard guidewire was used to establish the transport track between the left pulmonary vein and the inferior vena cava.A shape-memory alloy atrial septal occluder with a waist diameter of 20 mm was placed successfully and located correctly.TTE showed that the double disk unfolded well and that the clamping of the atrial septum was smooth.Immediately after the disc was revealed,electrocardiograph monitoring showed that the ST interval of the inferior leads was prolonged,the P waves and QRS waves were separated,a junctional escape rhythm maintained the heart rate,and the blood pressure began to decrease.After removing the occluder,the elevation in the ST segment returned to normal immediately,and the sinus rhythm returned to average approximately 10 min later.After consulting the patient’s family,we finally decided to withdraw from the operation.CONCLUSION Compression of the small coronary artery,which provides an alternative blood supply to the atrioventricular nodule during the operation,leads to the emergence of a complete atrioventricular block.
文摘Objective: To evaluate the therapeutic effect, safety and complications oftranscathetering Amplatzer device in the closure of patent ductus arteriosus (PDA) and atrial septaldefects (ASD) in children. Methods: Patients with PDA (n = 25) and ASD ( n = 16), confirmed byechocardiography, were treated by transcatheterization. Amplatzer occluder device was placed by thetranscatheterization with the image support of X-ray and transthoracic echocardiography ( TTE) . TheTTE, ECG and X-ray examination were engaged to evaluate the therapeutic results on the time pointsof 24 h , 1, 3 , 6, 12 months after the operation, and all these cases were engaged to the follow-upexamination. Results: The cardioangiographic diameter was 13.0-28.0 mm ([19.3+-4.9] mm) in ASD and2.0-7.7 mm ([3.9+-1.5] mm) in PDA . The diameter of the Amplatzer occluder selected were 13.0-30.0mm ( [20.6+-5.1] mm) in ASD and 4.0-12.0 mm ([6.6+-1.9] mm) in PDA , respectively. All the Amplatzeroccluders were placed successfully. There were no complications during and after the operation.Very small residual shunt was still found soon after the operation in 10 cases , and there were noresidual or recanalization after three months of the operation. The pulmonary artery pressure andheart size were significantly decreased in follow-up examination . Conclusion: Transcatheteringclosure with Amplatzer device is an effective, simple and safe technique in the treatment of ASD andPDA in children.

文摘Congenital heart disease （CHD） is the leading cause of birth defects, and its etiology is not completely understood. Atrial septal defect （ASD） is one of the most common defects of CHD. Previous studies have demonstrated that mutations in the transcription factor T-box 20 （TBX20） contribute to congenital ASD. Whole-exome sequencing in combination with a CHD-related gene filter was used to detect a family of three generations with ASD. A novel TBX20 mutation, c.526G〉A （p.D176N）, was identified and co-segregated in all affected members in this family. This mutation was predicted to be deleterious by bioinformatics programs （SIFT, Polyphen2, and MutationTaster）. This mutation was also not presented in the current Single Nucleotide Polymorphism Database （dbSNP） or National Heart, Lung, and Blood Institute （NHLBI） Exome Sequencing Project （ESP）. In conclusion, our finding expands the spectrum of TBX20 mutations and provides additional support that TBX20 plays important roles in cardiac development. Our study also provided a new and cost-effective analysis strategy for the genetic study in small CHD pedigree.
文摘Objective To evaluate the efficacy of minimally invasive perventricular device closure of ventricular septal defect(VSD). Methods Between September 2011 and February 2013, we collected 40 patients who underwent perventricular closure via a small lower sternal incision(minimally invasive group), aged 15.5±3.5 years(12 months to 32 years) with a body weight of 24.2±7.5 kg(10.8-58.0 kg). The mean size of VSD was 5.6±0.5 mm(2-14 mm). Another 40 patients were included as the surgical group, receiving the conventional surgical repair of VSD. The device of the minimally invasive group was released under the guidance of transesophageal echocardiography. Success rate, cardiac indicators, and clinical outcomes of the 2 groups were compared. Results The patients in the surgical group and those in the minimally invasive group showed similar results in success rate(both 97.5%). The procedure time, intensive care unit stay, hospital stay, and postoperative recovery time in the minimally invasive group were significantly shorter than those in the surgical group(58±21 minutes versus 145±26 minutes, 2±1 days versus 8±3 days, 5±1 days versus 16±6 days, 3±1 days versus 90±20 days, all P<0.05). The minimally invasive group had a higher incidence of conduction anomalies(17.5% versus 2.5%, P<0.05). In the follow-up period of 3-12 months, there was no new residual shunt, noticeable aortic regurgitation, significant arrhythmias, or device failure except for new complications in the surgical group. Conclusions The success rate of minimally invasive perventricular device closure of VSD under transesophageal echocardiography guidance is similar to that of conventional surgical repair, but the short-term outcomes of the minimally invasive approach is much better. Long-term follow-up is necessary to confirm the effectiveness of this technique.
文摘AIM:To investigate long-term efficacy of two different devices more than five years after percutaneous atrial septal defect(ASD)closure in adults.METHODS:All patients who underwent percutaneous closure of an ASD in the St.Antonius Hospital,Nieuwegein,The Netherlands,between February 1998 and December 2006 were included.Percutaneous closure took place under general anaesthesia and transesophageal echocardiographic moni toring.Transthoracic echocardiography(TTE)was performed 24 h post-procedure to visualize the device position and to look for residual shunting using color Doppler.All complications were registered.All patients were invited for an outpatient visit and contrast TTE more than 5-years after closure.Efficacy was based on the presence of a residual right-to-left shunt(RLS),graded as minimal,moderate or severe.The presence of a residual left-to-right shunt(LRS)was diagnosed using color Doppler,and was not graded.Descriptive statistics were used for patients'characteristics.Univariate analysis was used to identify predictors for residual shunting.RESULTS:In total,104 patients(mean age 45.5±17.1 years)underwent percutaneous ASD closure using an Amplatzer device(ASO)in 76 patients and a Cardioseal/Starflex device(CS/SF)in 28 patients.The mean follow-up was 6.4±3.4 years.Device migration occurred in 4 patients of whom two cases occurred during the index hospitalization(1 ASO,1 CS/SF).The other 2 cases of device migration occurred during the first 6 mo of follow-up(2 CS/SF).The recurrent thrombo-embolic event rate was similar in both groups:0.4%per follow-up year.More than 12 mo post-ASD closure and latest follow-up,new-onset supraventricular tachyarrhythmia's occurred in 3.9%and 0%for the ASO and CS/SF group,respectively.The RLS rate at latest follow-up was 17.4%(minimal 10.9%,moderate 2.2%,severe 4.3%)and 45.5%(minimal 27.3%,moderate 18.2%,severe 0%)for the ASO-and CS/SF groups,respectively.There was no residual LRS in both groups.CONCLUSION:Percutaneous ASD closure has good long-term safety and efficacy profiles.The residual RLS rate seems to be high more than 5 years after closure,especially in the CS/SF.Residual LRS was not observed.
文摘BACKGROUND Unroofed coronary sinus syndrome(UCSS)is a rare congenital heart disease,which has variable morphologic features and is strongly associated with persistent left superior vena cava(PLSVC).However,it is often difficult to visualize the left-to-right shunt pathway through the CS by transthoracic echocardiography(TTE).CASE SUMMARY A 37-year-old female was admitted to the hepatological surgery department of a hospital with complaint of subxiphoid pain that had started 1 wk prior.Physical examination revealed a grade 3/6 systolic murmur at the left margin of the sternum,between the 2nd and 3rd intercostal cartilage.The patient underwent echocardiography and was diagnosed with ostium primum atrial septal defect(ASD);thus,she was subsequently transferred to the cardiovascular surgery department.A second TTE evaluation before surgery showed type IV UCSS with secundum ASD.Right-heart contrast echocardiography(RHCE)showed that the right atrium and right ventricle were immediately filled with microbubbles,but no microbubble was observed in the CS.Meanwhile,negative filling was observed at the right atrium orifice of the CS and right atrium side of the secundum atrial septal.RHCE identified UCSS combined with secundum ASD but without PLSVC in this patient.CONCLUSION This rare case of UCSS highlights the value of TTE combined with RHCE in confirming UCSS with ASD or PLSVC.
文摘A 54-year-old female patient with congenital heart disease had a persistent complete left bundle branch block three months after closure by an Amplatzer ventricular septal defect occluder. Nine months later, the patient suffered from chest distress, palpitation, and sweating at daily activities, and her 6-min walk distance decreased significantly （155 m）. Her echocardiography showed increased left ventricular end-diastolic diameter with left ventricular ejection fraction of 37%. Her symptoms reduced significantly one week after received cardiac resynchronization therapy. She had no symptoms at daily activities, and her echo showed left ventricular ejection fraction of 46%and 53%. Moreover, left ventricular end-diastolic diameter decreased 6 and 10 months after cardiac resynchronization therapy, and 6-min walk dis-tance remarkably increased. This case demonstrated that persistent complete left bundle branch block for nine months after transcatheter closure with ventricular septal defect Amplatzer occluder could lead to left ventricular enlargement and a significant decrease in left ventricular systolic function. Cardiac resynchronization therapy decreased left ventricular end-diastolic diameter and increased left ventricular ejection fraction, thereby improving the patient’s heart functions.

文摘Percutaneous left atrial appendage(LAA)occlusion evolved as an alternative treatment to the patients who are contraindicated or cannot tolerate oral anticoagulants with nonvalvular atrial fibrillation(AF)at risk of stroke or systemic embolism.[1]Abnormal hemodynamic changes in elder atrial septal defect(ASD)patients cause remodeling of the left atrium,which eventually leads to right heart failure.[2]As the ASDs elderly are associated with a higher incidence of AF,simultaneous transcatheter ASD and LAA closure has become a new effective therapeutic strategy.However,only a limited number of articles involving cardiac tamponade complications have been published in the literature.What’s more,previous studies involving early hemodynamically irrelevant pericardial effusion after the procedure attribute to multiple repositioning attempts of LAA occluder or delivery sheath injured the atrial wall.
